Okay, well, how does bioluminescent jellyfish sound? Ice cream entrepreneur Charlie Harry Francis, founder of the U.K.-based Lick Me I’m Delicious, has developed the first-ever ice cream that glows in the dark. It was developed using a protein that gives the jellyfish its bioluminescence.

On his company’s website, Francis describes it: “We’ve been working with a company who have managed to synthesize a protein extracted from jellyfish that causes to occur. We’re using a specific form of this protein which reacts with calcium at a neutral PH, causing the protein to glow when it comes into contact with calcium.”

Remarkably, the ice cream also lights up when licked. It’s unclear what the ice cream tastes like, but Francis is known for his unusual custom flavors, cheddar cheese and roast beef among them. If you want to taste test the one with jellyfish protein, get ready to spoon out some moola. At $225 per scoop, it’s not for just anyone. But there is a cheaper knock-off version that Francis developed using quinine, which glows under black light. That one tastes like a gin and tonic.
